Kalanchoe plant named ‘LIZA’

ABSTRACT

A distinct cultivar of  Kalanchoe  plant named ‘LIZA’, characterized by its upright plant habit; dark green-colored leaves; large red purple-colored flowers with more than 15 petals per flower; and excellent postproduction longevity.

Botanical designation: Kalanchoe blossfeldiana.

Variety denomination: ‘LIZA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Kalanchoe plant, botanically known as Kalanchoe blossfeldiana, and hereinafter referred to by the name ‘LIZA’.

The new Kalanchoe is a product of a planned breeding program conducted by the Inventor in Hinnerup, Denmark. The objective of the breeding program was to create new freely-flowering Kalanchoe cultivars with large flowers, numerous petals per flower, attractive flower coloration and excellent postproduction longevity.

The new Kalanchoe originated from a cross-pollination made in Hinnerup, Denmark, of the Kalanchoe cultivar 2001-1855, not patented, as the female, or seed, parent with a proprietary Kalanchoe selection identified as 2000-0941, not patented, as the male, or pollen, parent. The new Kalanchoe was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Hinnerup, Denmark.

Asexual reproduction of the new Kalanchoe by terminal cuttings at Hinnerup, Denmark, by the Inventor, has shown that the unique features of this new Kalanchoe are stable and reproduced true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar LIZA has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘LIZA’. These characteristics in combination distinguish ‘LIZA’ as a new and distinct cultivar:

-   -   1. Upright plant habit.     -   2. Dark green-colored leaves.     -   3. Large red purple-colored flowers with more than 15 petals per         flower.     -   4. Excellent postproduction longevity.

Plants of the new Kalanchoe differ from plants of the parent cultivars in petal number and coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Kalanchoe, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Kalanchoe. The photographs were taken under diffuse natural light conditions on a sunny day at approximately noon in Hinnerup, Denmark.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘LIZA’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants used in the photographs and for the following observations and measurements were grown in Hinnerup, Denmark, under commercial practice in a glass-covered greenhouse for about ten to twelve weeks after the start of short day/long night photoperiodic treatment with average temperatures of 20° C. Plants used in the description and photographs were not pinched. Unless otherwise specified, the leaf description represents leaves from a vegetative plant.

-   Botanical classification: Kalanchoe blossfeldiana cultivar LIZA. -   Parentage:     -   -   Female, or seed, parent.—Kalanchoe blossfeldiana cultivar             2001-1855, not patented.         -   Male, or pollen, parent.—Proprietary selection of Kalanchoe             blossfeldiana identified as 2000-0941, not patented. -   Propagation:     -   -   Type cutting.—Terminal cuttings.         -   Time to produce a rooted young plant.—About two weeks.         -   Root description.—Numerous, fine, fibrous, and             well-branched. -   Plant description:     -   -   Form.—Upright plant habit with numerous compound cymes;             freely flowering. Actual plant shape will depend on whether             or not plants are pinched (apical terminals removed).         -   Branching habit.—Freely branching. Pinching (removal of             terminal apex) is not required but will enhance lateral             branch development.         -   Plant height at flowering.—About 30 cm.         -   Plant diameter at flowering.—About 26 cm.         -   Foliage description.—Arrangement: Opposite, simple. Size:             Leaf size is reduced after floral induction. Vegetative             plants: Length: About 9 cm. Width: About 7.5 cm.             Reproductive plants: Length: About 4 cm. Width: About 3 cm.             Shape: Oval. Apex: Obtuse. Base: Attenuate to obtuse.             Margin: Crenate; undulate. Aspect: Slightly concave.             Texture, upper and lower surfaces: Glabrous; leathery;             succulent. Color: Developing foliage, upper surface: 146A.             Developing foliage, lower surface: 146B. Fully expanded             foliage, upper surface: 147A. Fully expanded foliage, lower             surface: 147B. -   Flower description:     -   -   Flower type and habit.—Single flowers arranged in compound             dichasial cymes that arise from leaf axils. Upright             flowering stems. Freely flowering. Flowers persistent.         -   Natural flowering season.—Winter to early spring; flower             initiation and development can be induced under short             day/long night conditions.         -   Time to flower.—In the summer with 20° C. growing             temperatures, about 12 weeks of short day/long night             conditions are required to produce flowering plants. During             the winter with supplemental lighting and 20° C. growing             temperatures, about 13 weeks of short day/long night             conditions are required to produce flowering plants. Time to             flower is primarily dependent upon temperature and light             intensity.         -   Flower opening.—First flower open is the terminal flower at             the main axis and is followed by the opening of the terminal             flowers of the side branches of the inflorescence. About one             week after the first flower has opened, 50% of the remaining             flowers are open.         -   Post-production longevity.—Plants of the new Kalanchoe             maintain good leaf and flower substance for about five weeks             under interior environmental conditions.         -   Flower diameter.—About 2.4 cm.         -   Quantity.—Freely flowering, about 150 to 285 flowers per             plant.         -   Flower buds.—Shape: Narrowly oblong.
